Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a preamble transmission method, a power control method, a terminal,

This application claims priority to International Application No. PCT / CN2014 / 072098, filed with the Chinese Intellectual Property Office on February 14, 2014, entitled "PREAMBLE SENDING METHOD, POWER CONTROL METHOD, TERMINAL, AND DEVICE" All of which are incorporated by reference into this application.

The present invention relates to a mobile communication field, and more particularly, to a preamble transmission method, a power control method, a terminal, and a network side device.

The Universal Mobile Telecommunications System (UMTS) is a mainstream 3G wireless communication standard formulated by the Third Generation Partnership Project (3GPP). High Speed Downlink Packet Access (HSDPA) introduced in Release 5 and High Speed Uplink Packet Access (HSUPA High Speed) introduced in Release 6 to meet the ever-increasing rate requirement of users. High Speed Packet Access (HSPA), including Uplink Packet Access (HSPA), is introduced in UMTS to improve spectral efficiency, providing primarily higher data rates, lower latency, and higher system capacity.

In 3GPP Release 7, Continuous Packet Connectivity (CPC) features are introduced that support discontinuous transmit / discontinuous reception. This characteristic allows discontinuous reception and transmission to the UE (User Equipment). In the absence of data being transmitted, the uplink discontinuous transmission function allows the termination of the DPCCH transmission in the uplink to reduce uplink interference. In order to maintain power control and link synchronization, a UE (User Equipment) transmits DPCCH (Dedicated Physical Control Channel) control information within a discontinuous transmission period. In addition to further research into the 3GPP standard, the Further Enhanced Uplink Enhancement (hereinafter EUL Enhancement) feature has been studied in Release 12, which is referred to as a lean carrier, there is a technique called dedicated secondary carrier; The key idea of the technique is that when the UE is not transmitting data, the DPCCH is no longer transmitted periodically.

 Through repeated research and implementation, in the dedicated auxiliary carrier scheme, the UE transmits the DPCCH only when transmitting data in the uplink; Thus, when the UE initiates an uplink transmission, it has been found that the base station can not control the uplink transmission power because there is no scheduling of data for the UE for a relatively long period of time prior.

Obviously, the described embodiments are not all, but only some, embodiments of the present invention. All other embodiments that those skilled in the art, without any creative effort based on the embodiments of the present application, fall within the scope of the present application.

An embodiment of the present invention provides a preamble transmission method. The preamble transmission method provided in the present embodiment of the present invention is applied to a terminal, and the execution subject of the preamble transmission method may be a terminal device such as a mobile phone or a tablet computer. Referring to FIG. 1, FIG. 1 shows a flow chart of a preamble transmission method, and the preamble transmission method includes the following steps:

Step S101: Obtain a first uplink transmission gap, where the first uplink transmission gap is the time interval between the start of the current uplink transmission and the end of the last uplink transmission by the terminal.

Upon receiving the uplink grant signaling transmitted by the network side equipment, the terminal obtains a first uplink transmission gap in accordance with the received uplink grant signaling, Is the time interval between the start of the uplink transmission and the end of the most recent uplink transmission. In this embodiment of the invention, the network side device may be a base station, the network side device transmitting uplink grant signaling to the terminal, and uplink grant signaling used to indicate the time at which the terminal initiates the uplink transmission .

Step S102: If the first uplink transmission gap is equal to or more than one time threshold of the first predetermined time threshold, a preamble including DPCCH control information is transmitted to the network side device.

The obtained first uplink transmission gap is compared with a respective time threshold of a first predetermined time threshold; If the first uplink transmission gap is greater than or equal to one or more time thresholds of the first predetermined time threshold, the terminal transmits a preamble to the network side device, and the preamble includes a DPCCH.

In this embodiment of the present invention, when the terminal does not perform the uplink transmission or does not transmit the DPCCH to the network side equipment for a long time, the network side equipment transmits the uplink grant signaling to the terminal, The first uplink transmission gap is obtained when uplink grant signaling is received by the network side device to the terminal, and the first uplink transmission gap is obtained when the uplink grant signaling is received by the network side device, The transmission gap is the time interval between the beginning of the current uplink transmission by the terminal and the end of the most recent uplink transmission by the terminal. If the first uplink transmission gap is greater than or equal to one or more time thresholds of the first predetermined time threshold, the terminal may first request the network side equipment to control the uplink transmission power of the terminal according to the received DPCCH, And the preamble includes a DPCCH. In this embodiment of the present invention, when the preamble includes only the DPCCH, the preamble message can be interpreted as a DPCCH, i.e., the terminal directly transmits the DPCCH to the base station.

2, there is shown a detailed flowchart of a preamble transmission method according to an embodiment of the present invention, and the preamble transmission method includes the following steps:

Steps S201 to S204 are included, and step S201 is the same as step S101 in FIG. 1, and will not be described again here.

Step S202: It is determined whether the first uplink transmission gap is equal to or more than one time threshold of the first predetermined time threshold. If the first uplink transmission gap is equal to or greater than one of the first predetermined time thresholds, execute step S203; Otherwise, the step S204 is executed.

Step S203: transmits a preamble including DPCCH control information to the network side device.

Step S204: Preamble transmission including DPCCH control information to the network side apparatus is omitted.

From the above-described steps, in this embodiment of the present invention, if the first uplink transmission gap is smaller than the minimum time threshold of the first preset time threshold, the terminal transmits a Preamble ≪ / RTI > is not transmitted.

In the preamble transmission method provided in this embodiment of the present invention, the first predetermined threshold includes a first time threshold and a second time threshold. Referring to FIG. 3, transmitting a preamble including DPCCH control information includes the following steps:

Step S301: If the first uplink transmission gap is between the first time threshold and the second time threshold, the first transmission period of the preamble is acquired.

Step S302: In the first transmission period, a preamble including DPCCH control information is transmitted to the network side device.

In the preamble transmission method provided in this embodiment of the present invention, the first predetermined threshold further includes a third time threshold, and the first time threshold, the second time threshold, and the third time threshold are in ascending order .

3 shows a process for transmitting a preamble including DPCCH control information when a first uplink transmission gap is between a first time threshold and a second time threshold.

In this embodiment of the invention, when the first uplink transmission gap is between the second time threshold and the third time threshold, the process of transmitting a preamble including DPCCH control information is similar to the processor shown in Figure 3 :

Acquire a second transmission period of the preamble if the first uplink transmission gap is between a second time threshold and a third time threshold; In the second transmission period, the preamble including the DPCCH control information is transmitted to the network side device, and the second transmission period is longer than the first transmission period.

Similarly, if the first uplink transmission gap is greater than the third time threshold, obtain a third transmission period of the preamble; In the third transmission period, the preamble including the DPCCH control information is transmitted to the network side device, and the third transmission period is longer than the second transmission period.

In this embodiment of the invention, the first predetermined time threshold comprises one or more time thresholds, which may be predefined by the network or terminal or may be configured by the network side. The first predetermined threshold may be determined according to the power change of the uplink transmission physical channel of the terminal or the margin of the power control algorithm of the network side. If the change in the uplink transmission physical channel of the terminal is relatively slow, or if the UE is in a low-speed moving state, the time threshold in the first predetermined threshold may be set correspondingly larger; If the change in the uplink transmission physical channel of the terminal is relatively fast, or if the UE is in a high-speed moving state, the time threshold in the first predetermined threshold may be set to be correspondingly smaller. If the margin of the power control algorithm on the network side is relatively large, for example, if a relatively large margin is set for the initial DPCCH power of the UE, the time threshold in the first predetermined threshold may be set correspondingly larger; If the margin of the power control algorithm on the network side is relatively small, for example, if a relatively small margin is set for the UE ' s initial DPCCH power, the time threshold in the first predetermined threshold may be set to be correspondingly smaller.

In this embodiment of the present invention, a detailed example is preferably provided. The first preset threshold is set to include a first time threshold T0, a second time threshold T1 and a second time threshold T2, where T0 = 20 TTI or 40 ms, T1 = 40 TTI or 80 ms, T2 = 160 TTI or 320 ms. A TTI is a transmission time interval, indicating one subframe in UMTS, typically 2ms.

When uplink grant signaling is received, a first uplink transmission gap T is obtained; The transmission length of at least one preamble is defined according to a first uplink transmission gap T; If the first uplink transmission gap satisfies T (M-1) <= T <T (M), a preamble with a transmission length of L (M) is transmitted. When T0 < = T < T1, a DPCCH with one TTI is transmitted before data transmission; When T1 < = T < T2, a DPCCH with four TTIs is transmitted before data transmission; When T > T2, a DPCCH with 15 TTIs is transmitted before data transmission; The terminal initiates an uplink physical random access channel (PRACH) before data transmission.

From the above-mentioned example, it can be seen that, in the present embodiment of the present invention, the specific time point at which the preamble is transmitted or the time period during which the preamble is transmitted is determined according to the specific length of T. Before transmitting data to the base station, the terminal first transmits a preamble message including a DPCCH pulse.

In the present embodiment of the present invention, when T < T0, no preamble is transmitted.

In response to the preamble transmission method shown in FIG. 1, an embodiment of the present invention provides a terminal, which may be a terminal device such as a mobile phone or a tablet computer. A specific configuration diagram of the terminal is shown in FIG. 4, which comprises the following components:

(DPCCH) control information to the network side device when the first uplink transmission gap is greater than or equal to one or more of the first predetermined time thresholds, And a first transmission unit 402 configured to transmit a preamble.

In this embodiment of the invention, in order to instruct the terminal to perform the uplink transmission when the terminal does not perform the uplink transmission or does not transmit the DPCCH to the network side equipment for a long time, When delivering signaling, the terminal provided in the present invention receives uplink grant signaling carried by the network side equipment, the first obtaining unit 401 obtains a first uplink transmission gap, The transmission gap is the time interval between the beginning of the current uplink transmission by the terminal and the end of the most recent uplink transmission by the terminal. If the first uplink transmission gap is greater than or equal to one or more time thresholds of the first predetermined time threshold, the first transmission unit 402 transmits a preamble to the network side device, To control the link transmit power, the preamble includes a DPCCH. In this embodiment of the present invention, when the preamble message includes only the DPCCH, the preamble message can be interpreted as a DPCCH, i.e., the terminal directly transmits the DPCCH to the base station. In this embodiment of the invention, the network side device may be a base station.

Wherein the physical layer signaling transmitted to the terminal includes preamble duration information to instruct the terminal to transmit a preamble comprising a DPCCH if the second uplink transmission gap is greater than or equal to one or more time thresholds of a second predetermined time threshold, The preamble period information is a preamble transmission period.

Upon receiving the uplink grant signaling transmitted by the network side equipment, the terminal acquires a fourth uplink transmission gap in accordance with the received uplink grant signaling, and the fourth uplink transmission gap is determined by the terminal, The time interval between the start of the uplink transmission and the end of the most recent uplink transmission or the time interval between the reception of the current uplink scheduling and the reception of the most recent uplink scheduling by the terminal.

Step S1902: When the fourth uplink transmission gap is equal to or less than the seventh threshold, DPCCH control information is transmitted to the network side equipment using the transmission power of the latest DPCCH control information.

In this embodiment of the present invention, the network side device may be a base station or a radio network controller (RNC), the network side equipment transmits uplink grant signaling to the terminal, And is used to indicate the time at which link transmission is started.

The obtained fourth uplink transmission gap is compared with a seventh threshold; If the fourth uplink transmission gap is less than or equal to the seventh threshold, the terminal transmits DPCCH control information to the network side device using the transmission power of the most recent DPCCH control information.

The first threshold may be preset by the terminal, or may be set by the network and transmitted to the terminal.

In the present embodiment of the present invention, when the terminal does not perform the uplink transmission or does not transmit the DPCCH for a long time to the network side device, the network side device transmits the uplink grant signaling to the terminal, When instructing the terminal to perform uplink transmission using a method of transmitting information, the power transmitting the DPCCH by the terminal is the DPCCH power at the most recent uplink transmission. Since the channel attenuation change in the uplink transmission is affected by the transmission gap, i.e., the channel attenuation change becomes more significant as the transmission gap increases. When the transmission gap is small, the channel attenuation variation is not significant; Therefore, good initial power control of the DPCCH can be achieved using the previous DPCCH, so that the received power or the received signal-to-interference ratio (SIR) of the DPCCH stays at a level close to the target value. When the transmission gap is large, the channel attenuation change is significant; Thus, using the previous DPCCH can result in significant power control errors, resulting in a significant difference between the received power or the received SIR of the DPCCH and the target value. The UE may use a new method of setting the DPCCH power, for example, to reduce the variance of the DPCCH power control by using long term statistics gathering and power headroom, and to ensure the DPCCH power control performance, Power or power after filtering, or introduces an offset or power headroom based on previous DPCCH power, average DPCCH power, or power after DPCCH filtering.

A possible implementation is that the network does not transmit any physical layer signaling. In this case, the network and the terminal agree whether to use the power of the most recent DPCCH or the power of the latest DPCCH. The network side may also carry out signaling indicating how to set the DPCCH power using a Scope bit in the E-AGCH, a bit in the E-AGCH, or a channel with the same encoding scheme as the E-AGCH encoding scheme .
